Stainless, 4-inch constant-diameter pipes, and straight-through muffler outflow stock. Virtually eliminates backpressure and lowers exhaust gas temps. Throaty sound. 5-inch polished tip.

100 percent stainless system extends engine longevity by maintaining the turbine outlet EGT safely within the stock recommendation. The 3-inch Turbine Outlet Pipe, which replaces the smashed stock piece (see below), flows 728 CFM at 1 PSI, beating stock by 26 percent and the nearest competitor by 12 percent. The streamlined 4-inch exhaust pipe and tailpipe are formed of heavy-wall tubing with constant-diameter bends to slash backpressure.

The polished-stainless straight-through Monster muffler has an exclusive expansion chamber to dissipate the annoying mid-range drone that affects most straight-through designs. The high-flow muffler utilizes spun ceramic, very-high-temperature packing, and delivers a rich, throaty exhaust sound. And the 5-inch polished rolled-edge tip has an adjustable clamp for positioning on the tailpipe. Get it in your choice of chrome-over stainless or high temp black! (And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish)
